Java PersistenceUnit:jpaData-无法生成EntityManagerFactory

我已经设置了一个spring和hibernate项目，并得到以下异常：

Exception in thread "main" org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'entityManagerFactory' defined in class path resource [applicationContext.xml]: Invocation of init method failed; nested exception is javax.persistence.PersistenceException: [PersistenceUnit: jpaData] Unable to build EntityManagerFactory

有什么建议我应该在我的

entityManagerFactory

中更改什么吗？谢谢你的回答

注：我只想

在数据库级别阅读
，而不是
创建
，
更新
或
删除
某事物

更新

我已经在buildPath中添加了
ojdbc6-11.1.0.7.0.jar
 原因：java.lang.ClassNotFoundException:无法加载请求的类：org.hibernate.dial.Oracle
accroding异常，它错过了jar，请检查您的数据库配置，原因是：java.lang.ClassNotFoundException:无法加载请求的类：org.hibernate.dial.Oracle
由于发生异常，它丢失了jar，请检查数据库配置，检查您的hibernate.dial属性是否命名错误

试试这个：

org.hibernate.dialect.Oracle10gDialect

您命名了错误的hibernate.dialogue属性

试试这个：

org.hibernate.dialect.Oracle10gDialect

您真正的问题是找不到方言类：org.hibernate.dialogue.Oracle
，请为基础Oracle数据库版本使用合适的jar文件。@Vivien，您在使用maven吗？@Xstian yep我在使用maven。如何通过maven将库添加到运行路径？@Vivien，检查您是否正确导入了此依赖项…org.hibernate hibernate core您真正的问题是未找到方言类：org.hibernate.dialen.Oracle
